If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
x is 45.
x is 0.8
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
X = 135 and y = 15 Solved by addition and substitution
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
To find the x value where ( y = 15 - 3x ) and ( y = 0 ), set the equation equal to zero: ( 0 = 15 - 3x ). Solving for x, we get ( 3x = 15 ), which simplifies to ( x = 5 ). Therefore, the x value is 5.
x is 45.
x is 0.8

15 (x = 135)

Given that it does not change directly with x, and it is y = 15 when x = 5, find the value ofi y at x = 7
x+y=15 or y=x-15 x=-y+15 or you could graph and get (0,15) and (15,0) and thats it
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
